A strength coach tries to get InstaFit: Which popular exercise program is more effective – Kayla Itsines Bikini Body Guide or the Tone It Up Challenge?

This year, I decided to spice up my regular strength training and running routine by trying a few exercise programs that seem to be popular with the Instagram crowd due to their impressive #transformationtuesday progress pictures and heavy focus on their respective social media communities: the Kayla Itsines Bikini Body Guide (#BBG) and the Tone It Up Bikini Challenge (#TIUChallenge).

Besides trying something new for fitness last year, I was curious to see if these Insta-popular exercise programs are actually safe and effective from a strength training, functional movement and body composition point of view, instead of just another way to burn extra calories.
